DTC B1573: Short in Telephone Antenna Circuit; DTC B15CB: Telematics Transceiver Antenna Disconnected [11/2017 - 09/2020]: Description

This DTC is set when the DCM (Telematics Transceiver) detects an open or a short in the telephone and GPS antenna assembly (for Roof Side) circuit. The DCM (Telematics Transceiver) oscillates and receives 746 - 787 MHz, 824 - 894 MHz, 1850 - 1990 MHz or 1710 - 2155 MHz radio-frequency through the telephone and GPS antenna assembly (for Roof Side).

DTC No.	Detection Item	DTC Detection Condition	Trouble Area
B1573	Short in Telephone Antenna Circuit	Telephone and GPS antenna assembly (for Roof Side) impedance is lower than malfunction criterion for 10 seconds when engine switch is on (IG). (Short circuit)	DCM (Telematics Transceiver) Telephone and GPS antenna assembly (for Roof Side) Telephone and GPS antenna cord (No. 3 antenna cord sub-assembly) Telephone and GPS antenna cord (No. 2 antenna cord sub-assembly) Telephone and GPS antenna cord (instrument panel wire)
B15CB	Telematics Transceiver Antenna Disconnected	Telephone and GPS antenna assembly (for Roof Side) impedance is higher than malfunction criterion for 10 seconds when engine switch is on (IG). (Open circuit)	DCM (Telematics Transceiver) Telephone and GPS antenna assembly (for Roof Side) Telephone and GPS antenna cord (No. 3 antenna cord sub-assembly) Telephone and GPS antenna cord (No. 2 antenna cord sub-assembly) Telephone and GPS antenna cord (instrument panel wire)
